Field notes
The homepage frames adaptation as movement through a “sweet spot of difficulty,” rather than progression through a fixed textbook. Its visible language example is a Korean TOPIK 1 passage titled “학교 가는 아침,” marked with 12% unknown words and a one-minute reading estimate. The site also identifies Bloom’s six verbs as part of its learning model and places aviation drills alongside planned applications for mathematics, statistics, writing, and logical thinking.
